With over 30 years of expertise, Active Autowerke has meticulously designed this system to eliminate the undesirable factory exhaust notes, optimizing flow and resonance for a deep, throaty growl that befits an \"M\" car.\n\nThis exhaust system boasts key features such as \"Made in the USA\" construction, flex joints for vibration reduction, and a double-canned muffler to minimize resonance. It is designed to provide an 18+ WHP gain and a 30+ LB-FT gain over stock, along with quicker turbo spool. The system includes all necessary installation hardware and is guaranteed to fit all F80 BMW M3 and F82 BMW M4 models.\n\nWhen paired with the Active Autowerke F8X Mid-Pipe (sold separately), this rear exhaust section delivers the deepest sound and best performance according to the manufacturer. Dyno results show a peak gain of approximately 18 WHP and 30 WTQ when the full Active Autowerke exhaust system is installed. It is important to note that the Active Autowerke Full Exhaust System is recommended for, but not limited to, off-road or racing applications, and an \"Off Road Use Only Waiver\" must be signed and returned before the order ships.","brand":"Maad Maxx","offers":[{"title":"Default Title","offer_id":52662859792696,"sku":"ExhF8XM-REAR-G3","price":2374.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687075759.jpg?v=1784321593","url":"https:\/\/store.motormia.co\/products\/double-canned-rear-exhaust-section","provider":"MOTORMIA","version":"1.0","type":"link"}
